Im setting up a 40 breeder tank soon. I'm looking to have relatively low light but also would like to have the shimmer from the small light source. I was thinking about using 2 of these 10w leds. Would that be enough light- to have low light?

If it works let me know as thats much cheaper than the method I went for. Just keep on eye on it as the fans have tendency to burn out after a year or two. At least the ones on all my video cards have.

Anyone know approximately how high I should place these LEDs for a tank that's about 9-10" high if I'm aiming for medium/high lighting. Planning on mounting a shelf on the wall for these and I would rather not drill more holes than necessary.

Mine are mounted about 2 1/2 inches from the top of my 29 gallon tank. This puts them 12 inches off the substrate. It will also depend on how many you are running as there will be overlap where one led lights the same area as another led.

I will keep you posted. I'm hoping to under power it just a bit. If that won't ruin it. Even if the fan burns up, I would almost think it would be good enough without it. Maybe lol. I got if off eBay for $5 shipped so its a pretty decent deal.

I don't think that will be enough metal to passively cool it if the fan were to fail. These LEDs get hotter than I figured they would. I have no idea how people are cooling the 100 watt versions that some places sell.

I see no reason you cant under power the fan a bit. You just have to make sure it gets enough power to start up. Thats why a lot of pc's will start with there fans on high and then they drop back down to a slower speed. I would think if you ran it at 9v-10v rather than 12v it would start just fine.

I'm thinking I may mount the led drivers with rubber bands to the heat sink. I have a splash guard so if it falls of it should not hurt any thing.
